Over the past two winters, there wasn’t much ice cover on the Great Lakes. That changed with this month’s deep freeze.

Frigid temperatures have frozen more than 40 percent of Lake Erie’s surface, according to the National Oceanic and Atmospheric Administration or NOAA.  Scientists there predict ice cover could jump to almost 90 percent by Sunday.

This time last year, ice barely covered 2 percent of the lake.
